Recently, N-hydroxyindole derivatives have received much interest because of their unique structural motif and various biological activities. In this study, we report the first example of a Rh(III)-catalyzed reaction of arylnitrones with α-diazoketoesters or α-diazodiketones to produce N-hydroxyindole derivatives. Intriguingly, we could build the N-hydroxyindole scaffold by blocking the cleavage of

吲哚衍
生物由于其独特的结构基序和各种
生物活性而受到了广泛的关注。在这项研究中,我们报告的第一个例子是Rh(III)催化的芳基硝酮与α-二
氮酮酸酯或α-二氮二酮生成N-羟基
吲哚衍
生物的反应。有趣的是,我们可以通过选择性地阻断N-O键的裂解来构建N-羟基
吲哚骨架,同时优先消除α-二
氮酮酸酯或α-二氮二酮的酰基。
